Ukungakwazi ukusebenza
Ukukwazi ukusebenza kakuhle kwe-machining ngokuqhelekileyo kungcono xa i-annealed. Ukujika okukhulu, ukugaya, ukubhola kunye nokulungisa izinto ezirhabaxa kudla ngokugqitywa ngaphambi kokuba kuqiniswe kwaye kutshintshwe. Ngenxa yokuba i-H21 inezinga eliphezulu le-tungsten, ukhetho lwezixhobo, isantya sokusika kunye nolawulo lwe-coolant kufuneka kucwangciswe ngononophelo.
Unyango lobushushu
I-H21 idla ngokuqhotyoshelwa ngaphambi kokuba yenziwe ibe lukhuni ize iqiniswe ukuze ilungele ukusebenza. Iiparameter zokuqiniswa, zokucinywa kunye nezokulungisa kufuneka zikhethwe ngokobungakanani becandelo, umoya we-furnace, ubunzima obujoliswe kuyo kunye ne-die geometry. Ukufudumeza ngexesha lenkonzo kudla ngokuba kubalulekile ukunciphisa ukutshayiswa kobushushu.
Ukuwelda kunye nokulungisa
Ukulungisa ukuwelda kunokwenzeka ngenkqubo yokuwelda efanelekileyo, isinyithi esifanelekileyo sokuzalisa, ukufudumeza kwangaphambili kunye nonyango lobushushu emva kokuwelda. Kwii-dies zomsebenzi oshushu ezibalulekileyo, izigqibo zokulungisa kufuneka ziqwalasele umngcipheko wokuqhekeka, umahluko wobunzima, ubushushu benkonzo kunye nobomi besixhobo esiseleyo.
